ORIGINAL: shufflez

Wow Solo, quite the thread you've started! After reading all posts, i though of an eleborate comment, but... i don't have something! As i don't have any experience on FP's and hardly on CP's.

YOU ALSO HAVE EXPERIENCE WITH THE CX. THE CX HAS INSTANT RESPONSE AND LIKE STUMP3R NOTED, WE HAVE GOTTEN USED TO FLYING THE ROTOR BLADES - NOT FLYING THE FLYBAR. THESE SINGLE ROTORS SEEM VAGUE AND DISCONNECTED FROM THE INPUTS.

I know you're 'fighting' the FP, instead of 'proactively' controlling it. I've put the 4th and 5th packs 'through' my HDX today (got footage too! Post that later, i'm on holiday (again! )), to trim it all out and what i've noticed is that now i have way more space (although sloped grass hill) i can react much more in control instead of 'panic' reactions to keep it from hitting something. Immediatelly when the HDX came close to anything or even with the tail near the ground, i started to overreact/overcompensate, causing me to have to fight to get control back.

YES YOU DO UNDERSTAND WHAT WE ARE FIGHTING. EVEN THOUGH THE FALCON IS EXTREMELY DURABLE, WE STRIVE TO CONTROL THE HELI. THAT'S WHY WE ARE IN TRAINING. FIRST LEARN CONTROL, THEN MOVE UP TO A MORE SOPHISTICATED MACHINE. AND I AM SEEING THE ROTOR / FLYBAR TILT BEFORE THE HELI MAKES A MOVE AND I AM ADDING PREEMTIVE CONTROL, BUT A SUBTLE TOUCH IS TYPICALLY NOT ENOUGH TO CORRECT IT. PERHAPS MY INPUTS ARE TOO GENTLE? SPEAKING STRICTLY FOR MY OWN SITUATION, I DO SPEND THE MAJORITY OF MY TIME DIRECTING THE HELI BACK TO THE CENTER OF MY GARAGE. MY INPUTS ARE GENTLE AND SUBTLE. GIVEN THE AIR TURBULENCE IN THE GARAGE (ROTOR WASH) SUBTLETY IS FREQUENTLY NOT ENOUGH.


I put the stock carbon blades (hmm, maybe time for traininggear... or not! ) on for the flights today, instead of the 'weaker'/more flexible and shorter plastic blades and i've noticed much better response and more docile control. So you might be on to a good thing with the blade-modding.

I APPRECIATE THE TIP. NOTING THE CONING OF THE STOCK BLADES IT ESTIMATE THE TIPS OF THE BLADES BEING 2.5" (64 MM) ABOVE THE HUB. THAT IS A LOT OF CONING AND IT'S NO WONDER THE REACTION IS SLUGGISH! I WOULD EXPECT THAT CARBON BLADES ON THE FALCON WOULD IMPROVE RESPONSE. AND YOU SAY THE HDX WITH CARBON BLADES IS MORE DOCILE? THAT'S VERY ENCOURAGING. IF WE MOD THE STOCK BLADE, IT MAY SPIN FASTER, BUT IT WON'T BE ANY MORE STIFF. I NEED TO WORK ON THAT ASPECT.

About the twitches, how sure are you those aren't radio-glitches? Keep hearing about those when i'm at the LHS, apparently something you'll learn to live with or cause you to switch to 2.4Ghz . Is it true that some of the 'older' servo's sometimes cause to twitch/jitter themselves when they've continiously pushed/pulled (so not stayed in fixed position)? If so, maybe that's causing the glitch? I don't believe that anything external would cause such a sudden and hefty twitch in the flybar. Winds/draft would have to fight the rotational force, so that should be a more docile reaction... Maybe sun-rain (heavy electromagnetic static caused by major events on the suns surface)?

I DO APPRECIATE THE MANNER OF YOUR THOUGHT PROCESS. GLITCHES - I HAVE PLACED THE HELI AT FAST IDLE ON THE FLOOR AND MOVED ALL AROUND IT WITH THE STICKS CENTERED AND AGAIN WITH STICKS OFF-CENTER. I NEVER-EVER SEE SIGNS OF A GLITCH. THAT MAKES ME THINK THAT I WAS WRONG ABOUT GLITCHING. AS WAS MENTIONED IN AN EARLIER POST IN THIS THREAD, IT MAY BE ROGUE AIR CURRENTS FROM FLYING IN AN ENCLOSED AREA. THE HELI SEEMS TO HAVE THE SAME ISSUE WHEN FLYING OUTDOORS IN A LIGHT GUSTY BREEZE. AT THIS JUNCTURE, I BELIEVE THAT SIDE WINDS WILL REACT ON A CONED ROTOR IN A MORE RADICAL MANNER THAN A FLAT STIFF ROTOR. YOUR OPINION?

We all know you can take a hit, but why would you need to?! We're on here to learn right? Not to get talked out of flying, but to get into flying!

BEYOND OPINION THERE IS TRUTH. WITH ENOUGH OPINIONS STATED, WE CAN EXTRACT TRUTH - OR AT MINIMUM WHAT WE BELIEVE TO BE A COMMON FEELING. I'M SURE SOME OUT THERE THINK I'M JUST OVER THINKING THIS. PERHAPS I AM. BUT I AM LEARNING A LOT AND ENJOYING THE EXCHANGE.

But if you want a hit; maybe it's year of birth related?! (Sorry, that's something i say to my family most of the time when they cant get something working the way they want to i don't know if it's inappropriate here, but i'll take the hit if not ).

IN THIS COUNTRY, AT THIS TIME, WE DON'T SPEAK OF SUCH THINGS. WE ARE ENTIRELY TOO CONCERNED ABOUT PEOPLE'S "FEELINGS". SO YOUR COMMENT IS INAPPROPRIATE. BECAUSE THIS FORUM IS INTERNET BASED, AND THE INTERNET IS INTERNATIONAL, I SUPPOSE WE'LL HAVE TO TAKE YOUR COMMENT TO THE HAGUE FOR AN INTERNATIONAL TRIAL TO DETERMINE IF I CAN FEEL INSULTED OR NOT. AND I'M TRYING TO CONTAIN MY LAUGHTER AS I WRITE THIS KNOWING THAT YOUR COMMENT DOES HAVE SIGNIFICANT MERRIT!


P.S. I've managed to crash my CX2 today for the first time in 'ages'! After the 'heavy' and concentration-draining HDX 'flights' i picked up the CX2 for a good beating around the yard/garden, all is well until i got balsy trying a stall turn . FFWD (well, as fast as a CX can go), pull full back on the pitch, just a bit of right aileron and you have yourself a flying brick . Good thing i have my HDX and now my CX2 can be my beloved 'bashing around' baby, instead of my 'carefull, watch it!' baby .
THANKS FOR THE COMMENTS SHUFFLEZ. I WAS HOPING YOU WOULD THROW YOUR COMMENTARY INTO THE THREAD.
